High-wire walker Nik Wallenda said he battled wind and sand when he walked across a gorge near the Grand Canyon. He told Anderson that he's never been afraid of heights, and that he dreams of a walk in New York City someday.
Wallenda said he would want to walk on a wire between the Empire State Building and the Chrysler Building, or the mile across Central Park, or even across the Time Warner Center.
